HORSE HAY-FORK.

SPECIFICATION forming part of Letters Patent No. 233,533, dated October19, 1880. Application filed September 6,1880. (No model.)

To all whom it may concern:

Beit known that ILJOHN A. MGANULTY, a citizen ot the United States,residing at Indiana,in the county of Indiana and State of Pennsylvania,have invented certain new and useful Improvements in Hay-Forks 5 and Ido hereby declare the following to be a full, clear, and exactdescription ot' the invention, such as will enable others skilled in theart to which it apro pertains to make and use the same, reference beinghad to the accompanying drawings, and to letters or figuresof referencemarked thereon, which form a part of this specication.

Figure 1 is a side elevation, showing the fork as in readiness to beplunged into the hay. Fig. 2 is a side elevation, showing the fork as inposition when raised from the hay-load and carrying on its extended fingers a mass of hay. Fig-3 is a detail in section on line ac w of Fig.

2o 2. Fig. 4 is a detail on line y y, Fig. 2.

The design of the present invention is to produce an easily-operated,strong, and service` able fork for use in hay elevators and stackers 5and the novelty consistsvin the construction of the device and thecombination of the several parts of which it is composed, all as willnow be more fully set out and explained.

In the accompanying drawings, A denotes the bail or loop of the fork, bywhich it is at- 3o tached to or connected with the carriage of any hayelevator or stacker. This loop is preferably elliptical in form, andnear the lower part its sides or legs a are not brought together, butare prolonged for a considerable and proper distance. To and in theirlower ends are pivoted, at b, the lingers B. At the lower part of theloop A its sides or legs a are secured in place by the yoke or band O,which can be made of two pieces clamped to- 4o gether by bolts and nutsc, or these sides can be secured in any desired way or manner.

The central stem or rod, D, can be moved up and down between the sidesa, and to its lower end are pivoted, at b', the inner ends of .1,5 thefingers B. At its upper end this stem or rod D passes through a slot orhole in the yoke or band C about midway between the two sides a, and issecured to the elliptical ring E,

which is sustained about centrally in the loop A on the pulley or rollerL, and has movement 5o between the upper ends of the tlat cheek or sidepieces, F. These side pieces are fastened at their lower ends to andoutside the yoke or band G by the the same bolts c which unite the partsof the yoke together. This ring E can be raised or lowered by means ofthe looplever H, bent at h, and there pivoted, at f, between the upperends ot' the cheek-pieces F outside ot' the ring E. The long end ot'this lever H extends outside of the loop A, and can 6o be raised orlowered by means ot' the rope I, attached to the arm K, hinged in theouter part of H. This rope runs thence up and outward, and is operatedby the attendant according as the lingers B are to be opened or closed.

In the inner and opposite end of this looplever is pivoted the roller L,which thus comes inside of the ring E, and when the arm K is down itdraws down the long outer end of the 7o lever H. This raises theopposite short end H', and thus the roller L, acting inside theflattened ring E opposite to its joint of suspension, raises it up inits grooved path on the side a of the loop A. When these parts are inthis position the fingers B are closed and point downward, as shown inFig. 1, and in this condition the fork is in readiness to be let downinto the hay on the carriage. When thus let down the fingers can beopened, as 8o seen in Fig. 2, by raising the lever H, when they will beso extended under the mass of the hay that when the fork is drawn up bythe usual means or mechanism in hay-elevators the extended ngers willbear away a full 8 5 load ot hay. When the ngers are so extended theloop-lever H will be moved up on the side of A until the offset 7c onthe under side of the jointed arm K falls into the notch a on theoutside of a. Thus the fingers B 9o will be retained in this outspreadposition until the hay or straw has been carried by the movement ot' thefork on the elevator to the proper place of discharge on the mow orloft, when the arm K can be raised by drawing on rope L, and thusreleased from the notch a',-

then the weight of the hay will cause the fingers B to corne togetherand let the hay slide oi'; then the fork will be ready for again beingplaced into the hay for another load.

Having thus described my invention, what 1 consider new, and desire tosecure by Letters Patent, is-

1. In a hay fork, in combination with the loop A, having legs a, securedtogether by straps or yoke C, and the fingers B, pivoted thereto, andthe central stem, D, pivoted to ngers B, the ring E, hung between theside pieces, F, and lever H, whereby said stein is
